摘要： An object of the invention is to provide a simple method and apparatus for evaluating a collapse load of a structure with respect to ductile fracture in the case where a plurality of flaws exist in a cylindrical structure that receives a bending load. The invention is an evaluation method and apparatus in which a result obtained by calculating a collapse load while a flaw having the largest area among a plurality of flaws is considered as a single flaw and a result obtained by replacing a plurality of flaws with penetration flaws corresponding to the plurality of flaws and calculating a collapse load are compared with each other and the smallest collapse load is set to be a collapse load of a structure.
